I've read lots about stability and landing. I have a stock KR2. It's fine!!!!
You don't need to extend the fuselage length or put a bigger tailplane on to make it more stable. Those people who say there KR" is unstable haven't got it set up right with respect to the C of G. Just make sure your C of G is correct. A bigger tailplane means probably a bigger elevator, overall affect of both is a more stable aircraft until you move the larger, more powerful elevator. So now you need a smaller elevator, but then you won't have such an agile aircraft. It's all a waste of time and effort. If you lengthen the fuselage, yes you get a more stable aircraft until you move either rudder or elevator. Don't forget pitch or yaw control is a function of forces and length which can be exchanged for torque. More length more torque, overall affect of lengthening fuselage. Nothing but a waste of time and effort. Yes its more stable until you touch the controls, then the fact they are further from the centre of pressure makes them more powerful or the aircraft is just as light and twitchy. JUST GET THE Cof G RIGHT AND THE AIRCRAFT ORIGINAL DESIGN IS FINE! If its not broken, don't try to fix it. As for landing, its easy. Just fly along the runway in a slowly descending attitude, no flare or faffing or pilot induced oscillation, PIO. When the wheels touch, stick forward to keep the plane on the ground and close the throttle and wait for the tail to touch down. The biggest problem with the KR2 is you have to finish it, I bet 90% that get started never get finished. So don't worry about modifications or re-inventing the wheel, pitch sensitivity or flying or landing, just worry about finishing it, because most people won't ever finish the poor plane, but will sell it on again to the next person who will want to modify it and re-invent the standard KR2 design when there is nothing wrong with it, except from what they may have heard from someone who has zero flying experience of flying a Kr2 or from some bloke down the pub or flying club. I've got over 1,000 hours in three standard KR2's and they are fine... Final information for the day. Brakes. Trust me, you need the best brakes you can get. When its all going a bit wrong, wishing you had fitted better brakes won't be of much help. For examples of how to land a KR2 watch these or loads of other videos on youtube. https://www.youtube.com/watch?v=RSJXKZhHkfQ https://www.youtube.com/watch?v=9FJuTyf2sJc maiden flight of a friends KR2. https://www.youtube.com/watch?v=omBs9lCkBLI [https://ipmcdn.avast.com/images/icons/icon-envelope-tick-green-avg-v1.png]<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
